The suburb was originally known as Upper Dural until an early settler named Alex Hutchinson suggested that it should be called Galston after a town in Scotland. Galston has always been a rich agricultural area with many farms and orchards being operated throughout its history.

Historic Waddell Cottage still stands proudly today being built in 1866 by James Waddell as his family home.
